Because it doesn't suck that well!!

Merry Christmas guys and gals.

I am driving back to Bethel Alaska on the Kuskokwim River. Frozen optically flat, with a nice layer of 4-8 inches of powder on it. My engine just purring beautifully and....bllllllluuuuuaaahhhhhhh. It spools down to a stop. CRAP!! At least I am within sight of town.

So I check the gas; 1/4 tank left. Pulled the plugs, look good, no holes in the tops of the pistons. Temp on the engine was 120* F. plenty of cooling snow. So I put 5 gallons of gas into the tank and.....VRRROOOMMMMM!!!

So I learned something. And now I need to figure out where to put the stupid thing after I did all that work making up a mount to put it on the airbox.

it shouldnt be the pumps problem. wouldnt the pick up tube in the tank be the culprit?

Its not the pump! On firecats the fuel pump is mounted on the top right side of the bulkhead and no problems here! And when i race i try to keep as little fuel as possible to keep the weight down.

Ok, then it must be the pickup tube is not lieing flat on the bottom of the tank.

If you have too much line from the diaphram to the crankcase it sometimes won't get a strong enough pulse signal to run it properly also.

Ripperd, good point. I noticed when the motor has been running for awhile, the fuel line I used for the pulse line gets pretty soft and flexible. I think I will change it out for some polyurethane.

for the most part they dont use fuel line for pulse line. they use a heavy rubber line. more like a gas line for a car.
