<p class="MsoNormal"><span style="font-size:11.0pt">Took the TR4 out in an HPDE3 Session to test how she’s handling. I like how she handles but we have developed a lean condition. Revs fall flat between 4-5k then come back between 5-6k. Changed jetting and
that did not really help. Neither did hotted plugs. Lyman checked valve adjustments. That was not the issue either. It is odd however that we are blowing out the intake gaskets but no issue with the exhaust gaskets.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Lyman figures we are running about 90 hp at the wheel. Hopefully putting it on a dyno next month will help find the lean issue and maybe some more hp from this low compression engine. This is the motor (and
5 speed Toyota) that was in the Baja Car which needs low compression to deal with low quality fuel in Mexico. This fall a rebuilt high compression engine along with a 4 speed Triumph box will be installed.<o:p></o:p></span></p>
