I don't know how picky the Nova is on glow plugs, but the Picco is kinda picky. Maybe the newer versions of the Piccos aren't as picky? The glow plug deal is my only real complaint with the Picco. I ordered some P6S plugs for my P3 .28.
Neal - does Picco still make the P3 .28s or are they discontinued in favor of the Boost series?
Only the Boost now.... all turbo head
I use Nova plugs in my Nova's... OS in my OS, Picco in my Picco... pretty much with turbo engines its usually best to stick to the manufactures plug....some guys get away with running all sorts of plugs in all different engines, but I tend to play it safe....
The new Picco's are much looser then the older P3 28's.... same with the newer Nova's ..back in the day the old Nova's were nasty tight and guys had too many issues...when the target market is MT's they had to learn to better fit the pistons as a starterbox is much easier to use when dealing with a tight engine as opposed to a pullstart or rotostart ... Add in that the material quality of the engines was high so the breakin procedure usually lasted longer then the attention span of the user... These days the new Boost is fairly well fitted just like the Novarossi, much faster breakins and much less wear and tear on the OWB assemblies.....
On my engine I hand lap the pistons on any tighter engines.... reduces breakin time and drastically reduces the chances of a scuffed piston,,,,
