M38 Cdn Carb Help

[rob love]

A fuel pump is way more likely to produce less to no pressure than too much. They regulate by the spring under the diaphragm. Springs get weaker, not stronger.
A common problem, even in service, was the very fine particles of rust from the tank would make it through the course in tank filter, and either unsent the checkvalves in the pump or lodge in the float valve, causing flooding. The solution is to install an online filter, either before the pump or at the carb. The telltale sign this is the problem will be a very fine reddish sediment in the bottom of the float bowl.

If you used an original gasket kit, and the rubber was not happy with the ethanol, the bad results can occur quickly. Overall, they are a simple carb with little that can go wrong aside from those two diaphragm.

The calgary show is a great place to meet the guys from out that way. Only problem is there are way too many buyers vying for my time which cuts into the visitation time.

Morning Rob

Well I've had some success finally. I'm hoping this will get me moveable for the short term as I just ordered a new kit from Midwest Military.

Going through the TM was absolutely helpful in understanding the different circuit flows and cleaning (again and again) along the flow paths a few more times. I still can't definitively say I did anything different or a visible piece of gunk was dislodged....I'll take the win anyways. One thing I found funny in measuring the 3 metering rods I have (original, new kit and parts carb) and all 3 measure differently at 1.346, 1.319 and 1.356 respectively. Idle is good but it stumbles if I give it too much gas. I have the 1.356 rod in it now and may try the others.
I'm getting mixed opinions on the laminated base gasket...is it supposed to be solid or have 4 slots cut out, or have the V-shaped diffuser below? I'm using the solid one that came with the kit.

Update: Took her out for a test run and after only a few miles it really started to run/idle great. Too many ice creams will go down range now that the Mrs and me can go cruising again

I'll install a filter as suggested.
