Gas is cheap compared to engine rebuilding.
Google "lean running engine" for more info.

From my initial queries on the Forum, I may have to go to a PC III to get it in normal tune - no further blue-ing.
Question 1 - What are the effects of running lean - if it is only reduced power than I can live with that
Question 2 - Chief, I've searched the Mods/Tips and '1500' site, but can't find the original article on minutely adjusting a screw on the EMS to enrich the mix, can you point me at the thread, please.
Unfortunately (unless critical, in which case the children will have to fore-go little luxuries like food & I'll settle for mainstream "beer"), the PC III is beyond my budget until I get back into work.
Thanks
