Paul Amey Posted March 10, 2022 Report Share Posted March 10, 2022 When fitting carb. heat shields, where does one put them? Is it between the inlet manifold and the carb or is between the carb. and the air filter box? Link to comment Share on other sites More sharing options...

Peter Truman Posted March 11, 2022 Report Share Posted March 11, 2022 On the daughters Mk2 Spit I made my own Al shields one for each carb and mounted them on the back on the manifold to carb flange, the reason so I can remove the shields to improve access to the engine bay without interfering with the carbs. It reqd the flange studs to be removed and the holes threaded right thro the flange & replacing the studs with threaded bar. The reason I fitted heat shields was Fuel Vapourissues.

Make sure all surfaces are clean and flat as you don't want air being sucked in the joints. Iain Link to comment Share on other sites More sharing options...

Iain T Posted March 11, 2022 Report Share Posted March 11, 2022 Slight thread drift but is there any case for using a sealant ie Wellseal on any of the joints? I know this will make dismantling a problem but perhaps if not on all the surfaces? It could minimise potential leaks as the carbs only have two fixings.

Pete Lewis Posted March 11, 2022 Report Share Posted March 11, 2022 normally fine fitted dry you dont need sealer as it can break down with petrol and then you do get air leaks do make sure the faces are flat and clean no burrs from any previous gorilla hands at work Pete Link to comment Share on other sites More sharing options...
Iain T Posted March 11, 2022 Report Share Posted March 11, 2022 I've always fitted dry but following other sites posts some have indeed used sealants. I only bring this up as you know I'm playing around with the intake manifold vacuum gauge posted in the Tools Topic. A sealed intake manifold is a happy manifold!

Pete Lewis Posted March 11, 2022 Report Share Posted March 11, 2022 but its not sealed the throttle plates let the dreaded air inside 1 hour ago, Iain T said: following other sites if you do what the WSM says you get what Triumph intended Pub talk is good especially if you dont follow the myths do take care using the piston stop dont leave it in and go to run the starter that can be very expensive !!!!!

Arrives tomorrow, I'm disconnecting the battery first and putting a note there! I'll take the plugs out and also thinking of taking the rockers off so the engine turns over easily as I don't want to cause any damage to the piston. Whole the rockers are off I'll check the head torque. Off to change the engine oil and install new choke cable. Lovely day for it, the car park should be nice and dark🕯️ Link to comment Share on other sites More sharing options...

Pete Lewis Posted March 15, 2022 Report Share Posted March 15, 2022 Paul ...yes just to follow Ian's post ....whats a piston stop >>>>>>>>>>>>>> you can use a stop often made from an old spark plug so it protrudes into the chamber and you with care turn the engine by hand so the piston makes contact with the stop, mark the pulley turn the engine backwards to again make the piston touch the stop and mark the pulley top dead centre is exactly half/midway between the two marks on some engines the timing damper ring bonding fails and the ring moves around the pulley giving false timing positions if that sums it up and always remove the stop before you wander off and forget it ...
