Mock-up of a Walbro Carburetor

[5 Horse Fan]

I got this carburetor a while ago and had to get some parts for the throttle linkage.

Although it's small, it's quite an extreme carburetor.
1.100" Throttle Bore & 1.020" Venturi & Requires Fuel Pump

Snapped some photos of the Test Fit/Mock-up.
Only problems were the throttle plate chewing on the edge of the intake gasket & full throttle bends the cable pretty good.

nice carb but I wouldn't call it small with nearly a 28mm bore.... What is done to the engine?

The engine has a billet Rod, Dynocam 1.460" springs, & a new magnetron Coil.

is that a wb3a if so ran one without fuel pump worked good but kinda had somewhat of a gravity feed hard to tune eventually got it going pretty decent but when i was running it i did not fully understand all the adjustments like pop off and fulcrom height someday ill pull it out and tinker again with the flathead got to caught up with clones easy power for the money

Yeah, it's not a WB3a but it is bigger than that carb.
Will bolt up to a tillotson intake too, so it can be used on a clone with a round mikuni fuel pump.:thumbsup:

Post some results on how it runs on a mild build..

I found 3 round mikuni fuel pumps in the garage last weekend, so hopefully one of them works.

Found a cool spot to mount a one tang fuel pump.
