74' El Tigre dies out
« on: January 14, 2011, 08:27:13 PM »
The problem has officially been identified.  When it dies out and I restart it you can see small air bubbles building up in the fuel line where it connects to the pump.  It eventually dies out when too much air accumulates in the line up by the carb starving it.  Now I need to determine if the pump can be rebuilt or if a new one is in order.  I want to preserve the original fuel pump housing so an "aftermarket" pump will not work for this sled.  It will need either a new old stock original pump or a rebuild kit for the current pump.  Could also be the line in the tank is being restricted and it can't get enough fuel to stay running.

Found a pipe for it today and a trunk box.  This sled is going to be sooo sweeeet when I strip it down and restore it.  Project El Tigre has me pumped up on sledding right now!

Mikuni pumps are easy to fix. Kits are available may places. Dennis Kirk or HiPerf. Cat still sells all the replaceable parts too.
Current Sleds in Stock: None. SOLD OUT!

Pump rebuild kit was $6.00.  Didn't think it would be that inexpensive or easy to find, local dealer had it on the shelf.

A local dealer had it on the shelf????!!!!
That's getting to be unheard of.  Please don't keep us in suspense.  Who was it?

Lawn & Sport.  It was an aftermarket kit but it's just gaskets and a couple diaphrams.  The "round style" mikuni pumps must all take the same kit from that era.

Yep, you also could have gotten it from Dennis Kirk if you could not find the kit locally.  They are pretty easy to install as well, just be careful and note how you take it apart.
