I have a gas mixer problem I think?

[catfishhoward]

I just bought this 35 Johnson outboard model 35EL78R, 2 spark plugs. It says 50:1. I used regular unleaded gas and Quicksilver premium plus 2-cycle. I replaced the fuel screen at the fuel filter on the engine with a in-line filter on the gas pump line from wal-mart (glass filter).

It started easy and ideal good until I went to full throttled then it just stop. After that I could only go 2 mph, anything faster would stop the motor. It does smoke a little.

When I got home I cleaned the plug which were black and had gas mixer around the threads. I turned the motor over and let the block air out.

I took it out last night and used it for 2 hours at half speed and it worked great until I full throttled it again and it cut out and would then only go 2 mph again. The fuel filter looks clean.

Any ideas, Thanks Paul.

Re: I have a gas mixer problem I think?

I'd put my spark tester on it right when it fails to confirm proper spark at that point. If it's good, must be fuel (assuming good compression)
