Ok, this one is for the racers with lots of experience on the track! I'm finishing up my 45 WL racing motor. This motor has been very highly modified and is very hot. I have several MR racing linkerts that need rebuilding and I'm just wondering which one runs best. I have a aluminium MR3, bronze MR3, MR4 or two types of M53 [one has a 1 stamp next to the iddle needle and the second one has a #2 stamp. The #2 body has larger venturi and bowl bleed holes].
Which one works best and why? Thanks,
