Hi guys,

I've had my MT2 18SS for the past two months and I am now experiencing a problem at atartup. I have the rotostart system installed, never had any problem with it, gears are still pretty good with no apparent problems. Now here's the deal; when I try spinning the engine with my rotostart, the rotostart shaft spins freely without any resistance from the engine, also, when I am blocking the pipe's stinger to get pressure to build up in the fuel tank, the fuel does not go up the fuel line as it used to. If I replace the pressure line with a clean unused tube and blow air in it, to build up pressure in the fuel tank, the nitro goes up the fuel line and then I get resistance from the engine and get the usual "pop pop" sound and then it starts as it used to.

What could this be ? is my tuned pipe leaking pressure ?. Again, the rotostart looks fine, the rotostart backplate looks fine and my pipe does not look like it's broken anywhere (at least from the outside)

Any tips or clues would be appreciated.

Thanks

maby u caled try replaceing the fuel line
just a question how many bottles of fuel u been though( might be up for a rebuild or a new engien)

maybe your pressue tube has a leak?

oh and dose it hapen all the time becuase i dident get fuel to my carby but then i relised that it wasent open, i dont kow but that might be a problem

Replaced the pressure tube and only been through 2 gallons only. Rebuild would be a petty after only two gallons. The weird thing is that the engine runs fine once it's started but when the tank is empty and I need to refill, I have to go through the same little circus again.

What wasn't open ? the carburator ? mine looks fine too with 1/8 openig at idle. Gosh this is frustrating.
