Paul H Posted October 24, 2018 Report Share Posted October 24, 2018 Hi went to Sheringham for a day trip in the Vitesse . Outward trip was fine , return was fine until 40 miles in, then suddenly jerking kicking out of overdrive. Pulled over and couldn’t find anything obvious . Carrying on kangaroo actions in second , cured by foot to the floor , Happened in 3rd but not so vicious and in 4th but less again like a seesaw effect . To get home left overdrive alone and kept the revs high 3k plus and got home safely . I tested overdrive on the last mile and all ok. Total miles today 140 miles . We recently went to Ireland 1400 miles with no engine issues . My diagnosis is that it’s fuel related , all pipes are new, R9 where required , inline filters , hopefully will find a gremlin in the needle valve . The Irish trip was traditional points , last 300 miles converted to Accuspark electronic . Dizzy is Lucas , fuel pump has new diaphragm though will check Am I on the right track or missing something Paul Link to comment Share on other sites More sharing options...

The rest of the day starts on first tug. Will check on tank outlet and diaphragms Paul Link to comment Share on other sites More sharing options...
dougbgt6 Posted October 24, 2018 Report Share Posted October 24, 2018 Paul, I'm with Pete, (but we won't go into that!) rubber slivers requires carb clean up. Doug Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 25, 2018 Report Share Posted October 25, 2018 If you pop the tops off the carbs and and check the diaphragms if they are all wrinkled and wont refit a wash them in petrol will reform them back to size Pete Link to comment Share on other sites More sharing options...

Paul H Posted November 5, 2018 Author Report Share Posted November 5, 2018 UPDATE just started stripping down the forward CDSE carb - diaphragm is fine though found these 2 pieces of crud in the float bowl. They look too large to have got through the needle valve. The float bowl was full but not leaking suggesting the needle valve is not sticking Could this be the cause of the Kangeroo bucking ? Next I need to check the needle valves Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 5, 2018 Report Share Posted November 5, 2018 looks like the dreaded rubber slivers cut off the inside when fitting the fuel hoses i would have a look behind/remove the float valve Pete Link to comment Share on other sites More sharing options...

No wonder the car performance was similar to a bucking bronco whilest the slivers were forced through . I did check the offending items in the float bowl and one at least was a sliver of R9 Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 5, 2018 Report Share Posted November 5, 2018 Did you pump a good few squirts into jar , these blighters float back and forth in the tubes and block the valve just when you dont want them to. Pete 1 Link to comment Share on other sites More sharing options...
Paul H Posted November 5, 2018 Author Report Share Posted November 5, 2018 Hi Pete thanks for the tip. I’ve cleaned the valves and float chambers but will now pump a few squirts to clear the pipe . Paul Link to comment Share on other sites More sharing options...

Paul H Posted November 6, 2018 Author Report Share Posted November 6, 2018 I think Ive found the source of the contamination - see pic - I used a cotton bud to wipe the interior of a short connecting section by the carbs . The R9 is going soft and is most likely to be fake - Purchased from Fleabay and lesson learnt - I feel a trip to TSSC Open Day on December 2nd to buy some of the good stuff Paul 1 Link to comment Share on other sites More sharing options...

Pete Lewis Posted November 6, 2018 Report Share Posted November 6, 2018 the 5/16" Hose I had from club shop at duxford has SAE 30R 14T1 2018 and a bar code printed on it Pete Link to comment Share on other sites More sharing options...
rogerguzzi Posted November 6, 2018 Report Share Posted November 6, 2018 Hello All I had some hose like that on Spitty and after 1 year I could smell petrol and the outer was cracking and it had gone soft(its gone rock hard now its dried out! I used Gates Barricade the fuel injection type(Spitty has fuel injection) It is marked with name and type and multi fuel and bio fuel compatible etc You get what you pay for? but we all try to save the pennies! so it cost me more in the end and I could have lost the car if it burst(this is marked 225psi !!!)

rogerguzzi Posted November 7, 2018 Report Share Posted November 7, 2018 Paul Just buy from the club or a good supplier (gates etc) I would not touch the rest with a barge pole anymore(once bitten etc) If it look too good and cheap to be true! you know the rest?

Colin Lindsay Posted November 7, 2018 Report Share Posted November 7, 2018 This is the answer that seller gave to someone who posted negative feedback, when their 'R9' hose reacted with petrol within 24 hours: "Buy our Cohline Bio Fuel Hose then, not the cheapest." Speaks volumes, doesn't it? Link to comment Share on other sites More sharing options...
