I just acquired a used Honda BF40A. The idle set screw would not turn, but I was able to get it out with vicegrips. Examination under a microscope shows the upper threads dorked up.
Does anyone have the part number and/or screw size to order a replacement set screw from Honda, or elsewhere? I assume it is metric, and appears to be a SS pan-head phillips. My caliper measurements show it to be 0.152" diameter (3.86 mm) to the outer threads, 0.193"/10 threads (0.5 mm pitch), and 0.550" (14 mm) length. That would make it a non-standard fine-pitch thread. On McMaster-Carr, I can get a 3mm diameteter with 0.5 mm pitch or a 3.5 mm diameter with 0.6 mm pitch. But no 3.5 mm diameter with 0.5 mm pitch. |

Go to this site, Honda Parts Catalog blow-up drawings and excellent service:

They normally ship by US Postal and have good toll-free telephone support as well. |

Just buy the screw set (16028-ZV3-000) for about $8.00 and be done with it.
I can not find specs on it. Any listing I have is for the set (screw and spring)
If you can not find one locally, e mail me. We have 3 in stock. We can just stick it in an envelope and mail it. |

Thanks for the part numbers and link to the Honda catalog. I was able to find the parts there and order them. The parts I found are exactly as mike (hondadude) specified. Thanks! |
