Default Buggy Engine Will Not Fit

Ok there must be something I am doing wrong but I cannot figure it out.

I have a brad new Trinity Extech .21 engine for my new Losi 2.0 roller that will not come close to fitting.

After everything is mounted up, lined up and mesh set on the clutch bell to the spur gear my carb slide boot is smashed up against the center diff top plate. It seems that it is sitting to low and to far foward.

The only way I can get clearance is to twist the whole carb a 1/4 inch so that the high speed needle is sitting much lower that low speed which is bad news.

I am using the clutch wheel from the roller. I tried both the losi clutch and the trinity clutch. I even tried swapping out clutch bells on each set up and still wont fit.

Please help!!!!!!!!!!!!!!!!!!!!!!!!!

i am no expert but why is that bad news tat you have to turn the carb to get the slide away from the top plate? i also run a 2.0 and had the 1.0 before that and have had to do the same thing with both vehicles and have never had a single problem

It won't matter what engine you put in you will have the same "problem". Just turn the carb and go on with life. As long as there is clearence and the throttle linkage is not binding then what is the problem. How is the hsn lower than the lsn? sounds impossible

Just turn it. That's why engines were designed with the ability to move the carbs.

I've never seen a highspeed needle lower then the low speed needle before. Unless you've somehow put the carb on upside down... But then you would no be able to adjust the high speed needle as it would be facing the chassis.

I dremel my center diff top plate on my 1.0 so I can rotate the carb more and get the linkage as straight as possible. So do most of the other people I know. BTW, I'm running an ExTech in mine right now. May be a dumb question, but did you remove the carb and turn it so the LSN housing is facing the right side of the car?
