Briggs OHV & Vanguard / Model 35 block differences
« on: July 23, 2019, 11:13:03 am »
I am looking at ordering a new replacement block for a 20 hp Vanguard and there is multiple options.  Does anybody have a part # or know the difference between blocks?

Thanks

Briggs OHV & Vanguard / 35 ci oversize pistons ??

Looking for some 20 hp Vanguard 35ci oversize pistons for the ARC long rods.  I have spoke to ARC, PVT and carrier performance with no luck. 
Currently have cut down .020 and scrapped a cyl and need to go bigger, what is everybody using or doing??? New block? New sleeve?  We have 10 motors that are identical, so going the 38ci piston route won't happen.

Thanks

Briggs OHV & Vanguard / 20hp Vanguard rattles when shutting off.

Hi everyone
I have a model 35 Vanguard, a Performance V Twins short block with stock heads, shimmed springs, ARC flywheel and 2 bbl carb on gas.  If I run hard, when I shut it down it makes a rattle sound and a puff of smoke out the carb, it will do this once every 5 -6 races.
 It all started when my bumper got pushed into my rear tire and finished the race not realizing it was working harder than usual. I have checked the usual, flywheel key, valves, compression.

Any ideas what is happening?
